Like Dave, one morning I was unpleasantly surprised with Windows automatically installing Windows 10 (I credit it to a co worker who came in early, started my computer, and hit "yes" when prompted). Once installed, I didn't notice any problems running my programs. Windows 10 itself was a little bit different from 7, enough to be annoying at first, but I've gotten used to it to the point I think I will now install 10 on my home computer. There was an early security update that messed up our network settings, and they replaced Internet Explorer with Windows Edge, which I am not too crazy about.
